IMPROVEMENT IN MACHINES FOR FINISHING BOTTLE-NECKS.

Specification forming part of Letters Patent N 166,390, dated August 3,1875; application filed July 24, 1875.

To all whom it may concern Be it known that I, WILLIAM LANGWELL, ofAtterclifl'e, Sheffield, England, Kingdom of Great Britain, haveinvented certain Improvements in Machines for Finishing Bottle-Necks, ofwhich the following is a specification:

This invention has for its object more especially the finishing of theneck and mouth of glass bottles, by-shaping the neck and forming thereonthe mouth, but it is applicable to the shaping and finishing of otherglass vessels or receptacles, such as tumblers, gobblets, jars, 850.;and it consists general] y in a revolving spindle, carrying revolvingadjustable dies, a face-plate, a core or plug, and levers andconnections for operating and adjusting the. dies, all as hereinaftermore particularly described and claimed.

v In the drawings, Figure 1 is a side elevation of this invention, apart of the bearings being shown in section to more clearly illustratethe working parts. Fig. 2 is an end view of the same, showing the faceplate, dies, and plug. Fig. 3 is a section of the same through the line:0 :v of Fig. 1. Fig. 4 is a partial view in section, through the line11 v y of Fig. 1. Fig. 5 is a separate View of one of the adjustablearms with its pivoted die.

In the various figures the same letters are used to indicate thecorresponding parts.

a is the bed of the machine, and supports the parts shown in thedrawing, and also the forks in which the snap, which carries the bottleor other vessel, is rested while such bottle or vessel is being appliedfor the action of the dies. 1) b are the standards, provided with boxesI) and b, to receive the bearings of the machine, The box I) is formedwith an annular groove to receive the flange on the drum d. c is theshaft or spindle, to which the various parts are attached. It receivesits motion from the band or gear wheel f, operated by hand or otherpower, and revolves upon its bearings, drum d and face-plate e, to whichit is rigidly attached. Spindle 0 is slotted at s, and is perforated atits center to receive the rod g, which rod is operated by means of theconnecting-levers r, n, and o, and handle Upon spindle c are arrangedtwo sliding guide-heads, fully shown in front view in Fig.

3 of the drawings, designated by the letters h h, which are secured toeach other by the rigid connecting-rods w w. The sliding rod g isconnected with the guide-head it through the slot 8, and, by means ofthe levers r n 0, these heads, to the limit of the slots length, can heslid back and forth upon the spindle. As shown in Fig. 3, theseguide-head's have four perforations made diagonally through them, andthrough these perforations the Z- shaped arms are passed. These Z orzigzagshaped arms, as fully shown in Figs. 1 and 5, are at one endprovided with T-shaped heads, arranged to slide incorrespondingly-shaped grooves in the boss 11 5 their other ends passthrough slots 6 in the face plate 6, and upon them are hung, so as toturn freely upon their axes, the dies m. It is thus plain that thesearms 70, uncontrolled by the guide-heads h h, have a freedom of movementto and from the center of revolution of spindle c, and that, by reasonof their peculiar conformation, the movement back and forth of theguide-heads h h will cause these arms to recede from and advance towardthe spindle 0, and will open and close the dies 1 about the core or plugm. This core or plug m, as shown in the drawings, is rigidly secured tothe face-plate e, and is of a conical shape, but for some purposes itmay be more desirable to allow the core or plug freedom of revolution,and its shape can be changed to conform to the purpose and object towhich it is applied.

The dies 1, as shown in the drawings, have at their base, next to theface-plate, an annular square groove, adapted to form a flange upon theneck of the bottle at its month. But the form of the dies may be variedto adapt them to the production of any other desired result in themanipulation of bottles or other vessels, and they may be rigidlysecured to the arms instead of being hung, as shown. The end of rod g isannularly grooved, passed through an elongated opening in lever n, andsecured in place by a set-screw, which passes into the groove, andallows the rod free revolution. The boxes I) bare secured by metallicplates at 12, held down by screw-bolts.

The operation of my invention is as follows: A bottle being ready forthe action of this machine, is placed in a snap, the snap rested in theforks provided for the purpose, and the guide-heads, by means of thehandle 10 and connecting-levers, thrown back, so as to open the dies andallow the partly formed bottleneck to be advanced about the core or plugm and up to the face-plate e. The dies are then closed upon thebottle-neck. By advancing the guide-heads operated by the handle 1),held by the operator, motion is communicated to the machine throughpower applied through the medium of the band or gear wheel f, and theaction of the rolling-dies upon the bottle-neck will cause it to flareout and against the face-plate e, and in a very short space of time forma perfectly-flanged mouth.

It is apparent that the whole mechanism, with the exception of thesupporting and retaining parts, and the levers r n 0 10, revolves, andthat in order to efi'ect any difl'erent purposes in the shaping ofbottles or of other glass vessels, which can be accomplished byrevolving action, that it will be necessary merely to give ditferentform to the dies and the plug.

I claim as my invention- 1. The combination of arevolving face-plate andadjustable dies, with acentral plug or core, substantially as and forthe purpose set forth.

2. The combination of the sliding guideheads h h, with the arms k anddies thereto secured, Substantially as set forth.

3. The combination of therod g, with the spindle 0, guide-heads h h, andarms k, substantially as and for the purpose set forth.

WILLIAM LANGXVELL.
